Abstract

Przedmiotem wzoru użytkowego jest kotew strunowa, znajdująca zastosowanie do kotwienia górotworu, w szczególności w górnictwie podziemnym węgla kamiennego. Kotew strunowa posiada żerdź (1), składającą się z połączonych ze sobą obejmami (2) w wiązkę prętów (3) i ma w swym wnętrzu wzdłużny kanał (6) z jednym ujściem na zewnątrz (7) i z drugim ujściem na zewnątrz (9). Drugie ujście na zewnątrz (9) zlokalizowane jest na odcinku elementu rozporowego (5), znajdującego się wewnątrz żerdzi (1), w sąsiedztwie końcowego okucia (4). Na żerdzi (1), na odcinku elementu rozporowego (5), osadzona jest zewnętrznie nagwintowana tuleja (10), na którą nakręcona jest nakrętka (11) do nadawania naciągu wstępnego kotwi. Na zewnętrznie nagwintowaną tuleję (10) mocowana jest głowica iniekcyjna (12) mającą postać odcinka rury (13), zamkniętego z jednej strony końcówką tłoczną (14), a z drugiej strony wyposażonego w nakrętkę (15) do nakręcania na zewnętrznie nagwintowaną tuleję. Wewnętrzna komora (17) odcinka rury (13) ma średnicę większą od średnicy (d1) końcowego okucia (4) oraz długość nie mniejszą od odległości (L1) między zewnętrzną krawędzią (18) zewnętrznie nagwintowanej tulei (10), a zakończeniem (19) zewnętrznego okucia (4).The subject of the utility model is a string anchor, used for anchoring the rock mass, in particular in underground coal mining. The string anchor has a rod (1) consisting of interconnected clamps (2) in a bundle of rods (3) and has in its interior a longitudinal channel (6) with one outlet (7) and the other outlet (9) . The other outlet outside (9) is located on the section of the expansion element (5) located inside the rod (1), in the vicinity of the final fitting (4). On the rod (1), on the section of the expansion element (5), an externally threaded sleeve (10) is mounted, on which a nut (11) is screwed to give pretension of the anchor. An injection head (12) is attached to the externally threaded sleeve (10) in the form of a pipe section (13), closed on one side with a discharge nozzle (14), and on the other side equipped with a nut (15) for screwing onto an externally threaded sleeve. The inner chamber (17) of the pipe section (13) has a diameter greater than the diameter (d1) of the final fitting (4) and a length not less than the distance (L1) between the outer edge (18) of the externally threaded sleeve (10) and the end (19) the outer fitting (4).
